Seiyoku Tsuyo Tsuyo THE ANIMATION – Episode 1 (ES)

Nanase Nanase, a beautiful gyaru with a popular yang-kei (extroverted) boyfriend, feels constant dissatisfaction in their routine sex life. Her irritation peaks when she notices classmate Nozaki—a creepy otaku in the same committee—ogling her legs repeatedly. In a fit of frustration and teasing, she demands he expose himself, expecting something pathetic. To her shock, Nozaki reveals an enormous cock far surpassing her boyfriend's. As her built-up sexual frustration grows unbearable, Nanase impulsively uses his dick as a "dildo substitute" for a trial insertion. The overwhelming pleasure floods her body, erasing thoughts of her boyfriend as raw lust takes over. She becomes addicted to the intense, animalistic sex, leading to full-on cheating sessions filled with deep penetration, creampies, and complete surrender to carnal desire. This first volume captures the explosive beginning of her descent into obsession, highlighting the contrast between her glamorous exterior and primal urges.
